To all whom it may concern:

Be it known that LABMANDO E. 1301.10, a.

following is a specification.

My invention relates to improvements in torpedo guards for ships or vessels.

An important object of the invention is to provide apparatus of the above mentioned character, adapted to prevent the torpedo from striking the ship, retard its movement without causing an explosion thereof and permit of its capture.

A further object of the invention is to provide'means of the above mentioned character, so constructed that if the nose of the torpedo should contact with the guard in a manner to cause the exploding of the torpedo, such explosion would not do substantial damage to the ship.

A further object of the invention is to provide apparatus of the above mentioned character which is light, strong, and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of apparatus embodying my invention, the same being shown partly diagrammatically,

Fig. 2 is a transverse section, partly diagrammatically, of one protecting wing or vane, showing the manner in which a torpedo travels in contact therewith,

Fig-3 is a transverse section, partly dia grammatic, of the form of the invention shown in Fig. 1, V

Fig. 4 is'a similar view of a slightly dif ferent form of the invention, and, t

Fig. 5 is a similar view of a still difierent form of the invention.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, attention being called first to Figs. 1 and 3, the numeral 10 designates the hull of a ship or boat, which may be of any well known or preferred construction. Disposed upon opposite sides of the hull 10 are guard wings or plates 11, which are curved in cross-section, as clearly illustrated in Fig. 3. These guards or wings are Specification of Letters Patent.

inclined upwardly and inwardly, and their inner edges are attached to the hull 10, at or near its top, .and above the water level, by any suitable means. As clearly shown in Fig. 3, the outer edges of the plates or wings 11 extend downwardly a slight distance be neath the bottom of the hull 10. Any suit,- able means may be employed to rigidly attach the plates or wings 11 with thehull, but

I have shown truss-work 12, comprising diagonally arranged bars13, as shown.

The plates or Wings 11 may he made in various widths, and I have found that satisfactory results are obtainable by having these plates or wings made in substantially the same width as the width of the hull 10.

As shown in Fig. 1, the plates or wings 11 are coextensive in length with the hull, while the invention is in no sense restricted to this idea.

Pivoted to the rear end of the hull 10 is a main rudder 14L, operated by the usual means, and the movement of this rudder is imparted to pitmen 15, pivotally connected therewith and having pivotal connection with supplemental rudders 16, which are pivoted to the rear ends of the plates or wings 11, as shown at 17.

In Fig. l, the hull 10 of the ship is shown as having a slightly difierent sh ape in crosssection, and the plates or wings 11 are attached to the hull 10, at points 18, arranged beneath and spaced a substantial distance from the top of the hull. In this form of the invention, the plates or wings 11 pro ject downwardly to or beneath the bottom of the hull. The same truss-work 12 is employed to rigidly attach the plates or wings 1.1 to the hull 10.

In Fig. 5, construction similar to that shown in Fig. 1, except that the plates or wings 11 are reduced in width and their outer edges do not project near or beneath the bottom of the hull 10 but are disposed in a plane passing through the hull at a point near its central portion. However these plates or wings 11 have their free edges disposed a substantial distance beneath the water level, while their upper edges are arranged beneath and spaced a. substantial distance trom the top of the hull. The truss structure 12 is employed to rigidly attach the plates or wings 11 to the hull 10.

In connecticn with the forms of the invention shown in Fig 4 and 5, it is to be understood that the rudders 16 are to be attached to the plates or wings 11 the rudder let attached to the hulls 10", these rudders being operated by means shown in Fig. 1. a

In Fig. 2, I have shown diagrammatically, the operation of a torpedo 19, contacting with the plate or Wing 11; nose 20 of the torpedo, by being elevated above the outer wall of the body portion thereof, does not ordinarily contact with the plate 11. The torpedo will thus propel itself up the inclined plate or wing 11 and may be captured. Should the nose 20 contact with the plate 11, it will do so at the free edge of such plate. The torpedo 19 exploding at this point will not substantially damage the ship or boat.

It is to be understood that the forms of are to be taken as preferred examples of The V l-laving thus described my invention, I

claim:

The combination with-the hull of a ship or boat of guard plates arranged upon opposite sides thereof withtheir outer edges disposed beneath the water level and the plates beil'ig transversely inclined and extending upwardly for connection with the hull above the Water level, and truss struc tures connecting the plates and hull.

In testimony whereof I alliX my signature in presence oftwo Witnesses.
